Where are agricultural regions in less developed countries? The three primary types of ag in LDC’s are: Shifting cultivation- characterized by slash-and-burn ag- the clearing of land by slashing vegetation and burning debris , and using a select field (swidden) for only a few years before leaving it fallow for many years to recover the soil. Shifting cultivation is practiced most commonly in the tropics and other regions where soil quality is relatively poor for supporting ag. The process works well with few people, but grows inefficient as the number of people increases and more fields must be left fallow longer. Shifting cultivation has been looked down upon in recent years as the importance of the rain forests to the Earth’s ecosystem becomes more apparent.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
